Sofia has been a judge on AGT since season 15, which aired in 2020. Before that, she was busy on her hit show Modern Family, which ended its 10-year run in 2020.

While Heidi, Simon and Howie were judges on the spinoff’s first season, America’s Got Talent: All-Stars, which premiered earlier this year to positive reviews, Vergara was conspicuously absent.

However, he has made his big comeback as a judge on season 18 of the original competition series.

Howie Mandel, 67, was also seen arriving at the studio wearing a NASA bomber jacket over a black T-shirt with matching pants and white shoes.

The comedian added a pair of small circular sunglasses and gave a quick wave when he arrived before filming began.

Simon Cowell was also seen arriving at the location.

The 63-year-old English television personality looked fit in a black T-shirt, jeans, boots and dark sunglasses.

He donned well-groomed facial hair, styled his hair short and spiky, and had his hands full of electronic devices.

Simon has proudly shown off his slimmed-down figure since filming began last month, after losing around 42 pounds (three stone) following a diet overhaul.

The TV personality spoke candidly about her weight loss last year and he confessed that he sometimes indulged in a plate of toasted beans to avoid dining in restaurants.
